It is sometimes called Pálida in Portuguese. It is of apparent magnitude 2.78 and about 360 light-years from Earth, the faintest of the four bright stars that form the constellation Crux. As a subgiant, it has left the stage of a B-dwarf star at the main sequence, is now developing into a red giant and will one day end as a white dwarf. Delta Crucis is a Beta Cephei variable and changes its brightness subtly with a period of 1.3 hours. Its rotation is very fast, with a period of less than 1.3 days.
